Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667164, here are decompositions:

13 + 8667151 = 8667164
43 + 8667121 = 8667164
61 + 8667103 = 8667164
211 + 8666953 = 8667164
283 + 8666881 = 8667164
367 + 8666797 = 8667164
397 + 8666767 = 8667164
631 + 8666533 = 8667164

Showing the first eight; more decompositions exist.
